' It all 'urizom it may concern:

lie it known that I. luv Com. TERRY, a citizen of the thritcd States,residing at Monroe. in the parish of ()uachita and State ot' Louisiana.have invented new and useful l nu n'm'ements in l'l aylhesscs. of whichthe following is a specification.

This an. ontion relates to hay pi'esses, an'cl particulzirtyw to meansFor automatically dropping or inserting in position between the bales ofhay the division boards or blocks mnploycd to separate the bales.

The primarv object of the invention is to provide inc-ans tor moving thecage which holds the l'vloclc at the proper moment over the opening inthe halo chamber through which the division block is dropped into saidchamber, such means acting in timed accord with the plunger and heateror feeder whereby the insertion of the block at the exact time issecured and liability of damage to the press as a result of theinsertion ot the block at an improper time ob viatcd.

With these and other objects in view, the invention consists of thefeatures of construction, mn'ibination and arrangement of partshereinafter fully described and claimed. r tcrence being had to theaccompanying drawings. in which Figure '1 is a. side elevation of ahay-press embodying my invention, showing the parts of the droppingmechanism disposed for the forward movement of the cage to droppingposition by the plunger. Fig. 2 an en larged detail perspective view ofthe cage and associated parts of the dropping mechanism. 3 is a top planview on an enlat-god scale. showing the primary operating devices, Wartsappearing in section. Fig. .t is a section on the line l t of Fig. 3.Fig. 5 is a detail view of the ca or block holder. Figs. and T are viewson an enlarged scale showing the ditterent positions of the parts of thedropping mechanism when the cage is disposed in normal and droppingppsitions.

lietcrrins: to the drawing", 1 designates the Frame o t a hay press otthat type having a baling chamber provided with an extension 3 throughwhich the formed bales 4 move prior to discharge, and having hopper 5conununicating with the top of the haling cl'nnnbcr for the feed of the.hay thereto. said hopper being equipped with a condenser t' g t anysuitable construction and operated in any preferred manner.

T designates the plunger which compresses the hay in the baling chamberto form the halo. and 9 the pivotally mounted heater or feeder which"forces the. hay from the hopper into the haling chamber. This heater.or feeder is mounted for pivotal movement on the frame and is pivotallyconnected with actuating bracket. arms 9 connected to and mo able withthe plunger and slidably mounted in guideways formed between the top ofthe frame and horizontal guide strips 10 secured thereto. The feeder isprovided with the usual striker 11 adapted to engage and force thedivision block from its cage or holder into the billing chamber, ashereinafter described.

The rear wall of the hopper is formed by a cage 12 which is adapted tohold the division block 13 which is to be, introduced. This cage isprovided with a side opening 14 for the insertion of the block and witha slot or opening 15 in its top for the entrance of the striker 11 whenthe cage is in drop ping position. to force the block down into thebaling chamber. In the present instance, I have shown the application ofmy i11V611- tion to a press in which the cage 12 is movable forwardlytl'irough the action of the plunger over an opening 16 through which thedivision block is introduced into the hating chamber, but with slightvaria tions in the form and construction of the parts, the invention maybe employed in connection with presses whose cages are shifted into andout of dropping position by a. tilting. an oscillatory or any other kindof motion. In this case the :age. is fixed at its base to a carrierblock or plate 17 having a central rear extension 18 provided with slots19 loosely receiving bolts 20, by which said block is slid-ably mountedupon the hay chamber frame. to permit a limited back and forth movementof the. cage. The body of the cage is connected with the free extremityof ti" 1 arm by an inclined brace 21, which also serves as a contact armor member by which the cage may be shifted, as hereinafter described.Hinged or pivoted to the lower rear portion of the cage, as at 22, is acontact plate or apron 23 normally having the upwardly tilted positionshown in Fig. 6 and provided with a central slot or recess or apron isadapted to be swung downward to a horizontal position to he in the path2& to receive and accommodate the brace 21. when it. is so tilted. Thesaid contact plate."

of contact springs 25 carried by the bracket arm 9, so that at theproper time period the cage will be shifted forwardly to droppingposition. In its normal upwardly inclined position, the apron lies outof the path of movement of the contact springs, so that the bracket armsmay reciprocate back and r operating wheel or disk 26 the lower edge ofwhich projects downward through a slot 27 in the top of the extension 3so as to be engaged by the underlying moving bale 4, by which the wheelwill be turned in a retro grade direction. The wheel is preferablycomposed of an armed spider or hub 28 fixed to a shaft 29 j ournaled insuitable bearings 30, and a series of toothed segments 31 each having areduced portion secured to one of the arms of the spider by a bolt- 82,which is adjustable in a slot 33 formed in the spider arm, whereby thesegment may be radially adjusted with relation to the shaft 2t By thisconstruction the diameter of the toothed wheel may be varied, as circumstances may require, to vary the speed of rotation of the wheel tooperate the parts of the dropping mechanism controlled thereby atdifferent periods or at greater or less intervals in the operation ofthe machine.

The shaft 25) is provided at one end with a crank disk 34 having anarcuate slot 35 receiving a suitable wrist projection 36 on the free endof a pit-man 37, the opposite end of which is adjustably pivoted, as at38, to the adjacent end of a rod 39, which end of the rod is slidablymounted in a guide 40 011 the adjacent side of the frame. The oppositeend of the rod is bent downwardly and rearwardly at an angle and is'pivotally connected to the lower end of a compoundly curved vibratoryoperating lever 41 fulerumcd between its curved arms on a bolt or fixedfulcrum pin 42 carried by the frame. On this bolt or pin is alsofulcrumed at its lower end a swinging bar or post 43 to the upper end ofwhich is intermediately fulerumed an inclined trip or shifting lever41-. The lower forward end of the lever l -tis formed to provide ahandle 45 for manual adjustment in initially setting the parts and isconnected with the upper rear arm of the operating lever 41 a link 46and with the hopper or any suitable portion of the frame by a coiledspring 4:7, operating when permitted to throw said lever to shiftingposition. The upper rear end of the lever t-tis pivotally connected witha crank arm 48 on the contact plate or apron J3, bv which the movementof said lever to shifting position will effect the depression of saidapron into 'the path of the contact springs 25. As the lever 44 isconnected with the apron in the manner described, it obviously must befree to shift forward and backward with the cage 12, :which freedom ofmotion is permitted by fulcruming said lever upon the swinging snp'port.18. lVhere\the cage is shifted into and ont of dropping position in anyother than by a back and forth reciprocating mo tion, the mode ofmounting the lever 44: may vary as occasion demands. It will be understood, of course, that the spring 4.? permits of the shifting movementdescribed and supports the lever 44 and cooperating parts in properposition, in addition to its function of depressing the contact apron,the construction therefore being such as to permit ample flexibility ofmotion of the operating part to prevent liability of the same hangingand become injured in their operative movements. The lower arm of thelever (H is further connected by a link tt) with a crank arm 50 formedor provided upon one end of a rock shaft 51 journaled in suitable.bearings at the forward end of bracket arms 52 fixed to the adjacentends of the guide bars [0 and extendingat an upward and forward angletherefrom so as to leave lsufl'ieient space beneath them for the freemovements of the apron and contact springs. The shaft 51 is providedwith a crank or U-shaped portion 53 which extends beneath the brace orcontact arm 21 and is adapted to act thereon when the shaft isrockedforwardly to shift cage rearwardly from dropping to normalposition. The connection between the link 49 and arm 50 is pref-' erablyof an adjustable type in order that the extent of 'tln o\v of the crank53 may be varied to shift the cage the required distance and no more.Such a connection may be provided, as shown in Fig. 2, by forming thepivotally connected ends of the link and arm with a series of openingsfor the passage of the pivot pin or bolt 54.

In the operation of the press, it will be understood that the beater andplunger operate in the usual way to feed and compress the material.Assuming that the parts of position shown in Fig. '7, with the wrist pin36 at the limit of its downward movement and the rear end of the slot 35of the disk 34 in engagement therewith, it will be understood that onthe upward and rearward movement of said. crank disk and pin in therotation of the operating wheel 26 by the feeding bales t, the pull uponthe connecting rod 39 during the ensuing halt revolution of the wheelcauses the lower arm of the operating lever 4-1 to beswung upwardly, bywhich the/lower front arm of the lever t t will bedrz wn downwardagainst the resistance of the spring -17, thus placing 1 l5 the droppingmechanism are in the normal 20. c the lever 41 and .pulling the rod-39rear-i ,wardly, thus bringing the pin 36 down into said spring undertension and disposing the upper arm of the lever 44 at the limit of its:(pward movement to hold the apron 23 tiltupwardly or retracted, thusallowing the s rm advance of the contact arm 21 to permit the cage to beshifted forward to dropping position without interference therefrom.When, however, the Wrist-pin 36 reaches the highest point in its path ofmovement,

as shown in Fig. 1, and the slot 35 isdisposed in rear of the verticalcenter of the crank disk, the spring 57 is free to contract and drawsthe long arm of lever44 upward, thereby communicatin reverse motion totheforward .end of the slot, '50 that the crank disk will continuetomove -without affecting, the wrist-pin,' which-remains at rest until at in engaged by the rearend of uch movement -of 'the lever 44 swin therear arm of said lever downthe slot.

ward y, bringing the apron 23 to a hori;

zontal position and simultaneously turning the shaft 51 to move thecrank forward. Hence on the ensuing forward movement of l the plunger,and while the beater or feeder is at rest, the contact springs 25 willengage the apron and force the cage forwardly into dropping positionabove the opening 16, as illustrated in Fig. 6, allowin the divisionboard or block 13 to-=d1'op rom the cage through said opening onto theplunger, by

which it will be temporarily supportedr Whenthe. plunger movesrearwardly the block will be released and will drop down into the balingchamber in rear of the com pressed material or will be forced downward,thereinto by the striker 11 on the downward movement of the feeder 8which occurs at this. time. It will thus be seen that the block will bedropped at the proper moment to be moved forward with the material bythe plunge-non its subsequent stroke,- so that. the liability of damageto the apparatus by the dropping of the block pm, transmits forwardmotion to the rod 39- at an improper time in the movement of the plungerwill be effectually obviated. As the plunger moves forwardly again therear end of the slot 35 again engages the. wrist through the ,link 37 toreturn the levers 41 and 44 to normal position and again place' thespring 47 under tension. in which operation the'apron will be tiltedupwardly to an 1noperativeposition and the crankl53 swung rearwardly toretract the cage, thus reset ting the parts for subsequent uperalioxn Itwill be underst od that at this stage when contacts 25 to have movementwith 4 t e p unger and feeder without affecting the 'ward and the cageis retracted the attendant or op-' rawings, the construc-' tion andmodeof operation of the block dropping mechanism constituting my inventionwill bereadily understood, and it will be seen that, a mmhanism'of thischaracter is provided which-is positive in action and I operated in,timed vaccord with the movements otthe plunger and feeder for insertinga division block inposition at the proper time in the operation of ,thepress, thus preventing any. possibility of injury to the press from theln'sertion of a block at an improper period in the operation of the pluner.
